Problems solved by technology

[0004] Because a variety of industrial waste residues and waste liquids contain many valuable substances, if they are discarded, it will not only cause waste of raw materials, but also cause pollution to the environment. So can PVC residues, PVP residues, waste Plastics, alkyl vinyl ether (VOE) distillation raffinate, animal and vegetable oil refining waste activated clay (or waste activated carbon) and other components are used as the main raw materials, and are made into excellent performance through processes such as dissolution, polymerization, modification, and grinding. Waterproof adhesives have not been publicly reported so far. Therefore, how to use industrial waste residues and waste liquids to produce waterproof adhesives is a technical problem that those skilled in the art need to solve.

Abstract

The invention relates to a waterproof adhesive prepared by a plurality types of industrial residue and liquid waste, and the problem of preparing waterproof adhesive through industrial residue and liquid waste can be effectively solved. The method comprises the following steps by weight: adding 20-25% of VOE raffinate and 25-35% of PVP residue in 35-45% of PVC raffinate pretreatment liquid, heating up to 70-75 DEG C, dropwisely adding 2-5% of azodiisobutyronitrile solution, heating up to 80-85 DEG C, reacting for 2-2.5h to obtain a multi-element copolymer resin adhesive solution; using 65-75% by weight of multi-element copolymer resin adhesive solution, 8-14% of asphalt, 3-7% of waste activated clay, 5-10% of waste plastics and 1-4% of used oil as raw materials, and grinding 1 / 3 asphalt, used oil and spent bleaching earth to prepare modified activated clay; dissolving the waste plastics through the PVC raffinate pretreatment liquid, mixing the solution with the rest used oil and asphalt, heating to dissolve the mixture, stirring for 30-45min, adding the mixture in the multi-element copolymer resin adhesive solution, adding the modified activated clay, uniformly mixing the ingredients, and regulating the viscosity through the PVC raffinate to obtain the waterproof adhesive. By adopting the waterproof adhesive provided by the invention, industrial waste is effectively utilized, the preparation method is simple, and the environmental pollution is reduced.

Description

technical field [0001] The invention relates to chemical industry, in particular to a waterproof adhesive prepared by using various industrial waste residues and waste liquids. Background technique [0002] With the rapid development of industry, the amount of various industrial waste residues (liquids) by-products is constantly increasing. Many industrial waste residues (liquids) are hazardous wastes. If they are not handled well, they will become the main source of pollution that pollutes the environment. An environmentally friendly society is extremely disadvantageous. Although the state now supports the establishment of hazardous waste disposal centers in various provinces and uses incineration or landfill methods to dispose of hazardous waste, this has not fundamentally solved the pollution problem of these hazardous wastes. Harmful sulfides and nitrogen compounds produced during incineration pollute the air and water sources, and will form long-term hidden dangers dur...
